ABSTRACT:
A BCC phase hydrogen storage alloy capable of storing approximately 4.0 wt. % hydrogen and delivering reversibly up to 3.0 wt. % hydrogen at temperatures up to 110° C. The hydrogen storage alloys also possess excellent kinetics whereby up to 80% of the hydrogen storage capacity of the hydrogen storage alloy may be reached in 30 seconds and 80% of the total hydrogen storage capacity may be desorbed from the hydrogen storage alloy in 90 seconds. The hydrogen storage alloys also have excellent stability which provides for long cycle life.
